      How reproducible:

      Always

      Steps to Reproduce:

      *Create a Cluster Logging instance.

      apiVersion: "logging.openshift.io/v1"
      kind: "ClusterLogging"
      metadata:
        name: "instance" 
        namespace: "openshift-logging"
      spec:
        managementState: "Managed"  
        logStore:
          type: "elasticsearch"  
          retentionPolicy: 
            application:
              maxAge: 10h
            infra:
              maxAge: 10h
            audit:
              maxAge: 10h
          elasticsearch:
            nodeCount: 3 
            storage: {} 
            resources: 
                limits:
                  memory: "4Gi"
                requests:
                  memory: "1Gi"
            proxy: 
              resources:
                limits:
                  memory: 256Mi
                requests:
                  memory: 256Mi
            redundancyPolicy: "SingleRedundancy"
        visualization:
          type: "kibana"  
          kibana:
            replicas: 1
        collection:
          type: "fluentd"
      

      *Run the must-gather to collect Cluster Logging data.

      oc adm must-gather --image=$(oc -n openshift-logging get deployment.apps/cluster-logging-operator -o jsonpath='{.spec.template.spec.containers[?(@.name == "cluster-logging-operator")].image}')
      

      *Check that the command execution is hung indefinitely.

      $ oc adm must-gather --image=$(oc -n openshift-logging get deployment.apps/cluster-logging-operator -o jsonpath='{.spec.template.spec.containers[?(@.name == "cluster-logging-operator")].image}')
